Laravel Collections - la function collapse()

Pour cette 4e partie nous allons évolué encore un peu plus et cette fois parlé de la fonction collapse

#Description

Si tu as bien suivi ce que l'on a dit sur la méthode chunk() dans la partie 3, collapse() sera facile !

C'est l'exact inverse, en gros, collapse() recolle les morceaux !

#Exemples d'utilisation

**Code source #1 : on 'chunk' et on 'collapse' **

1$languages = collect([

2 "php",

3 "python",

4 "javascript",

5 "go",

6 "c#",

7 "java",

8 "cobol",

9 "basic"

10]);

11$chunked_languages = $languages->chunk(3);

12echo "<h2>CHUNKED</h2>" . PHP_EOL;

13print_r($chunked_languages);

14

15$collapse_languages = $chunked_languages->collapse();

16echo "<h2>COLLAPSED</h2>" . PHP_EOL;

17print_r($collapse_languages);

1$languages = collect([

2 "php",

3 "python",

4 "javascript",

5 "go",

6 "c#",

7 "java",

8 "cobol",

9 "basic"

10]);

11$chunked_languages = $languages->chunk(3);

12echo "<h2>CHUNKED</h2>" . PHP_EOL;

13print_r($chunked_languages);

14

15$collapse_languages = $chunked_languages->collapse();

16echo "<h2>COLLAPSED</h2>" . PHP_EOL;

17print_r($collapse_languages);
